摘要
沥青路面作为我国公路主要的路面结构形式,在高级、次高级路面中占有很高的比例,约为80%。因其具有地质条件适应性强、行车舒适、维护方便等优点,而被广泛用于高速公路。在高速公路通车后,因行车荷载作用、外界环境影响以及设计、施工中存在的不足,沥青路面会逐渐出现多种路面病害,主要有裂缝(纵向裂缝、横向裂缝、网(龟)裂);变形(车辙、推移、波浪或搓板、沉陷、拥包);松散(坑槽、磨光、松散、剥落)和泛油及其它四大类。而其中裂缝是最为普遍的,也是养护中首先遇到的问题,是预防性养护工作的主要内容之一。

And the most common and the first problem in maintenance are cracks, which is the major task for preventive maintenance.
